A checklist of earthworm species hitherto recorded from North Eastern Region (NER) of India is presented. In total, 128 species/subspecies belonging to 26 genera spread over 9 families are listed. Of these, 72 species are recognized as endemics, 18 as near endemics, 5 as native peregrines and 32 as exotics. The checklist includes literature citation to the original description, type locality, important synonyms and the state-wise distributional records for each species/subspecies.

Abstract Estuaries in Brazil are highly threatened environments and habitat loss is the main influential factor for the increase in the number of strandings of Antillean manatee (Trichechus manatus) calves in the north-eastern region of the country. The aim of the present study was to analyse and quantify the spatiotemporal dynamics of mangroves in the state of Paraíba and the association with manatee calf stranding events. The study area encompassed 10 remaining mangroves along the coast of the state, four of which were located within protected areas. Information on the mangrove forests was obtained from satellite images from the last four decades. Data on stranded Antillean manatee calves were obtained from a databank with records from 1980 to 2019. The data were analysed using geoprocessing techniques and statistical analyses. The results demonstrated changes in the mangrove forest over time, with larger areas existing during the 1980s, reductions in the following periods but a slight increase in the last decade. The number of stranded Antillean manatee calves increased over the years, with stranding events concentrated mainly on the northern coast of the state. The smallest number of stranding events occurred in the 1980s, when the mangrove forests were larger. Our findings confirm that the integrity of mangroves is of extreme importance to the maintenance and sustainability of Antillean manatee populations.

Despite the discovery of several new plant species from India every year, there is dearth of information on species of orchid, especially from the North Eastern Region . As a detailed survey seemed necessary for reliable documentation, we looked into the diversity of orchids in Tripura state. We document the first records from the state for 12 species of orchids, including two genera (Crepidium Tausch and Dendrolirium Blume). Geographical distributions along with detailed descriptions and photographs of the species are provided.

Background: Banana (Musa Paradisicia) is considered as one of the most important fruit crop across the globe. India is the largest producer of banana in the world with an output of 29 million tons per year on average. Assam, a state in the north eastern region of India, is one of the major banana producing state in the country. Banana is an important horticulture crop grown in Assam with some significant socio cultural importance. The production of banana in Assam accounts for 2.4 per cent of its total production in the country.Methods: The paper is an attempt to study the rate of growth and instability of area, production and productivity of banana cultivation in Assam and to compute the relative contribution of area, productivity and their interaction to the change in production of banana in the state. The study is based on secondary data for the period of 2003-04 to 2017-18. Compound annual growth rates are computed for estimating the growth trends of area, production and productivity of banana in Assam whereas Cuddy-Della Valle index of instability is used to estimate the instability.Result: The results of this study revealed positive growth in area, production and productivity of banana with low instability in the state. The productivity effect has been found marginally greater than the area effect on production of banana in the state during the reference period.

This research is based on the PACE recommendation and in this paper we will showcase some of the results. Our main purpose was to describe and analyse possibilities to achieve a moral and religious education by both family and school actors, as well as to come up with an inventory of suggestions for the improvement of this two-fold type of education. For this article we will only focus on a supportive objective, namely identifying the state-of-fact of religious and moral education in the North-Eastern region of Romania, more specifically the item concerning the effectiveness of religion and the belief that it provides answers to some problematical issues in the lives of the subjects selected for the study.

The Bodo of the North Eastern region of India have their own kinship system to maintain social relationship since ancient periods. Kinship is the expression of social relationship. Kinship may be defined as connection or relationships between persons based on marriage or blood. In each and every society of the world, social relationship is considered to be the more important than the biological bond. The relationship is not socially recognized, it fall outside the realm of kinship. Since kinship is considered as universal, it plays a vital role in the socialization of individuals and the maintenance of social cohesion of the group. Thus, kinship is considered to be the study of the sum total of these relations. The kinship of the Bodo is bilateral. The kin related through the father is known as Bahagi in Bodo whereas the kin to the mother is called Kurma. The nature of social relationships, the kinship terms, kinship behaviours and prescriptive and proscriptive rules are the important themes of the present study.

Background: Malaria is endemic in various parts of India particularly in the North- Eastern states with Plasmodium falciparum-the most prevalent human malaria parasite. Plantderived compounds have always received tremendous importance in the area of drug discovery and development and scientific study of traditional medicinal plants are of great importance to mankind. Objective: The present work deals with the computational study of some antimalarial compounds obtained from a few medicinal plants used by the tribal inhabitants of the North-Eastern region of India for treating malaria. Methods: In silico methodologies were performed to study the ligand-receptor interactions. Target was identified based on the pharmacophore mapping approach. A total of 18 plant-derived compounds were investigated in order to estimate the binding energies of the compounds with their drug target through molecular docking using Autodock 4.2. ADMET filtering for determining the pharmacokinetic properties of the compounds was done using Mobyle@RPBS server. Subsequent Quantitative-Structure Activity Relationship analysis for bioactivity prediction (IC50) of the compounds was done using Easy QSAR 1.0. Results: The docking result identified Salannin to be the most potent Plasmepsin II inhibitor while the QSAR analysis identified Lupeol to have the least IC50 value. Most of the compounds have passed the ADME/Tox filtration. Conclusion: Salannin and Lupeol were found to be the most potent antimalarial compounds that can act as successful inhibitors against Plasmepsin II of P. falciparum. The compounds Salannin and Lupeol are found in Azadirachta indica and Swertia chirata plants respectively, abundantly available in the North-Eastern region of India and used by many inhabiting tribes for the treatment of malaria and its symptoms.

To the North Eastern Region (NER) of India, lie the unexplored states of the Indian Union. This region holds a unique place in the federal structure of India. This article attempts to scrutinise the diversity of NER, along with the potential of the National Cadet Corps (NCC) as a medium to change, uplift and assimilate it with pan India. The article aims to comprehend how NER can accommodate the regional identities and cultural affinities with Indian mainstream identity through the intervention of NCC at college and university level. The methodology of this article is based on secondary resources such as published books, journals, web pages, reports, newspapers and online sources. The article is analytical and descriptive in nature based on thematic approach.
